Large scale features of the Earth can be represented with mathematics. The western side of the East European Craton is associated with the zone, and it can be clearly defined seismically, as shown here: https://www.sciencedirect.com/science/article/pii/S1611586419300034.
The mathematics of the convection rolls system fit to the alignment of the Teisseyre-Tornquist Zone and its Danish counterpart Sorgenfrei-Tornquist Zone. The seismicity follows the pattern of polygons very accurately, as shown here by numbering the adjacent polygons. When the alignment follows 10 polygons in exactly the same way, the accuracy and regularity indicates that the line of seismic activity is indeed affected by this pattern.
This is a main feature of Europe’s geology, and it coincides with the estuary of the Danube river into the Black Sea.
The shift from Sorgenfrei-Tornquist Zone to Teisseyr-Tornquist Zone also fits mathematically to the pattern of convection rolls, as shown here.
